TiWi-C-W

Integrated 802.11 b/g/n WLAN Module

This stand-alone WLAN (IEEE 802.11 b/g/n) module simplifies the work of adding Wi-Fi connectivity to your products on one of the smallest footprints available. The TiWi-C-W module’s breadth of capabilities ensures a straight-forward integration with your product design, including a pre-loaded cloud connectivity agent for LSR’s TiWiConnect™ platform.

The TiWi-C-W module is able to support both hostless operations with client applications running directly on its application processor, as well as hosted operations utilizing a device’s existing microcontroller via a serial UART interface. Development time and complexity is dramatically reduced for a hosted application, as LSR’s new TiWiConnect LIFT software offers a simple, intuitive protocol for the embedded software developer. This is the simplest module on the market to integrate Wi-Fi into your product.

Additional customer specific antennas can be added to certification for little or no cost

Video Transcription

The TiWi-C-W Development Kit featuring TiWiConnect from LSR demonstrates cloud connectivity features you should consider for your product’s next design cycle. Device-to-cloud functionality in this kit can be integrated using our small-footprint reference designs to add the TiWi-C-W Wi-Fi module to your product. Let’s get started.

Getting to know your kit

The form-function of the TiWi-C-W’s development kit was designed to provide numerous LED displays to help demonstrate the ability to control “attributes” of the demo kit remotely from a web app. In addition, the kit features a temperature sensor, IR light sensor, and 3 push button’s to also allow you to demonstrate the ability to send commands up to the cloud and viewed from the web app. You will also find a Power On/Off switch, a pin-hole Reset button, a batter compartment in back for housing 2 AA batteries, as well as a port for optional USB powering of the kit.

Getting the kit online

The first step toward experiencing what TiWiConnect offers is getting your kit online. First, put the kit into “Config Mode” by holding the third switch (labeled, “wake”) while turning the power switch to the “ON” position. Continue holding the switch and button in these positions until you see the Multicolor LED blinking blue several times.

Next, connect your mobile device to the wireless network named “TiWiConfig” followed by a series of numbers. These numbers correspond to your kit’s unique device ID. Your device ID is located on a small card included with your TiWi-C-W Development Kit.

Once connected, open a web browser on your mobile device (Chrome is preferred), and visit http://192.168.0.1.” Click the “WiFi Setup” button to scan for nearby networks.

Select the local internet-connected Wi-Fi network you would like to connect the kit to, such as your home or business’ official WiFi network. Enter the network’s password, then press the “Connect” button to complete the setup process.

Register your kit

In order to use your kit, you must complete a brief online registration. First, visit the TiWiConnect Server URL included with your kit and log into your account. If you don’t have an account, take a moment to sign up. Once logged in, navigate to the “Devices” section of the homepage and click “Add Device.”

Enter the “Device ID” number and “Device PIN” number included with the kit. Click “Add Device” to add it to your account.

Using the kit

Once your kit is connected to the internet and registered, you are ready to experience the interactive capabilities provided to the kit by the TiWiConnect platform. Once the kit is configured for your internet-connected WiFi network, it will attempt to join that network each time it is powered on. That means that there is no need to complete the setup process each time you wish to use the device.

First, turn the power switch to the “ON” position. The multicolor LED will light green to start, then pulsate while the kit joins the WiFi network. If the join is successful, the LED will blink 3 times solid green. If the join fails, all three LEDs will slowly blink and “Config Mode” will start after 10 seconds allowing you to re-configure for your Wi-Fi network.

Once the device has joined a Wi-Fi network, the green “Network Activity” LED blinks periodically, indicating the kit is connected to the TiWiConnect server. If a connection fails, the red “Status LED” blnks, which may indicate a weak signal or low battery.

Visit the TiWiConnect Server URL included with your kit or use our mobile app to log into your account. Navigate to the “Devices” page and click “View” for this kit. Devices can be identified using their unique Device ID. With the kit connected, you can monitor “Ambient Light” and “Temperature” values updating every 15 seconds. If you press one of the pushbutton switches on the device, the corresponding status will update shortly thereafter. This demonstrates how TiWiConnect allows a connected device to be monitored remotely from web and mobile apps.

Set the multicolor LED by clicking a color swatch within the web app. This initiates a remote command to the kit triggering the multicolor LED to adjust shortly after issuing the command. This demonstrates how TiWiConnect provides remote command features to a connected device from web and mobile apps.

Congratulations! You have now experienced how the TiWi-C-W provides more than just Wi-Fi connectivity. Integrating LSR’s TiWi-C-W module leveraging the TiWiConnect platform can elevate your product to the cloud providing new levels of interactivity for your customers and service personnel through web and mobile apps. For more information, reference your Quick Start Guide.
